The Profession of Nursing: Roles, Education, and Regulation
The history of nursing practice is a testament to the profession's evolution from ancient informal caregiving to the specialized, evidence-based practice it is today. Today, nursing is recognized as a vital component of the healthcare system, with over 29 million nurses globally. In Washington State, the term “nurse” has a specific legal definition that defines the requirements of a licensed professional.
The Evolution of Nursing Practice
The journey of nursing reflects a transformation driven by cultural, social, and scientific changes.
Ancient Foundations: In early civilizations, caregiving was often a family responsibility, with women playing a significant role. The Roman Empire established a disciplined system, including first aiders (Capsaril), trained orderlies (Immunes), and military hospitals (Valerudinaria) where Medici treated patients with surgery or herbs.
The Christian Era: Fabiola founded the first hospitals, offering care grounded in Christian tradition.
The Founder of Modern Nursing: Florence Nightingale gained fame during the Crimean War (1854–1856) for implementing sanitation reforms that drastically reduced mortality rates. Her work led to the establishment of modern nurse education programs.
Professionalization in the U.S.: In 1863, Clara Barton established the American Red Cross. The 20th century saw the formation of the American Nurses Association (ANA) and the International Council of Nurses (ICN) to promote standards and ethics.
Contemporary Nursing: Since the 1970s, the profession has emphasized evidence-based practice, advanced practice roles, and a focus on patient advocacy and holistic care.
Detailed Nursing Roles and Pathways
In Washington State, there are six legally defined nursing-related roles for those caring for patients in a medical setting.
1. Healthcare Assistant (HCA)
An HCA provides essential personal care and support to patients, helping with daily activities while assisting nurses and other medical staff.
What They Do: They assist with bathing, grooming, dressing, toileting, and feeding. They also prepare meals, perform light housekeeping, take vital signs, and provide social engagement and emotional support.
Where They Work: Hospitals, nursing homes, assisted living facilities, clinics, and patient homes.
How to Become One: Requires a high school diploma or GED and completion of approved training programs, including a 75-hour requirement in Washington State.
2. Medical Assistant (MA)
An MA performs both administrative and clinical tasks, primarily in doctor's offices.
What They Do: Administrative tasks include scheduling, managing records, and billing. Clinical tasks include taking vital signs, recording histories, drawing blood, giving injections or medications as directed, assisting during exams, and performing EKGs.
Where They Work: Most commonly in physicians' offices, but also in hospitals, urgent care, and dental offices.
How to Become One: Requires a high school diploma plus a certificate/diploma program (less than a year) or an Associate’s degree (2 years). Washington requires passing the WA Medical Assisting Exam.
3. Certified Nursing Assistant (CNA/NA-C)
CNAs provide essential direct patient care under RN or LPN supervision.
What They Do: They assist with bathing, grooming, dressing, feeding, and mobility. They also monitor vital signs and act as the "eyes and ears" for the clinical team by notifying nurses of condition changes.
Where They Work: Primarily in nursing care facilities (35%) and hospitals (33%).
How to Become One: Involves a short, state-approved course (4–8 weeks), 130 hours of coursework, 30 hours of clinical training, and passing a state certification exam.
4. Licensed Practical Nurse (LPN/LVN)
LPNs provide basic patient care and are crucial for patient comfort, safety, and monitoring.
Responsibilities: Monitoring vitals, administering prescribed medications and injections, changing bandages, treating wounds, and documenting patient care.
Where They Work: Nursing and residential care facilities are the largest employers, followed by hospitals and home healthcare.
How to Become One: Requires a high school diploma or GED, completion of a state-approved practical nursing program (typically 1–2 years), and passing the NCLEX-PN exam.
5. Registered Nurse (RN)
An RN is a licensed professional who coordinates and provides patient-centered care.
Core Responsibilities: Performing physical exams, recording medical histories, administering medications, developing and implementing nursing care plans, and coordinating care with specialists like physical therapists and pharmacists. They also advocate for patient rights.
Education and Licensing: Requires a nursing diploma, Associate Degree in Nursing (ADN), or a Bachelor of Science in Nursing (BSN). Candidates must pass the NCLEX-RN exam.
6. Nurse Practitioner (NP/APRN)
An NP is an advanced practice registered nurse with graduate-level education and clinical experience.
Core Responsibilities: NPs possess greater autonomy and can perform many duties traditionally associated with physicians. This includes diagnosing and treating acute and chronic conditions, ordering and interpreting lab results, and prescribing medications.
Education and Licensing: Candidates must complete a Master's or Doctoral level education in a specialty area, pass a national exam, and be licensed by the state board.
Education in Okanogan County
Nursing education has evolved from hospital-based repetitive practice to modern programs emphasizing the scientific basis for nursing actions.
In Okanogan County, education began in the 1970s with an LPN program through Wenatchee Valley College (WVC) in Omak. By 1986, the program added an Associate Degree in Nursing (ADN), and students can now earn a Bachelor's of Science in Nursing (BSN) locally. Roughly half of the nurses working in Okanogan County are graduates of the WVC program. North Valley Hospital, like other facilities in the county, typically hires nurses upon graduation from this program.
Governance and Regulation
Nursing practice is regulated at the state level by Boards of Nursing (BONs) through Nurse Practice Acts (NPAs). In Washington State, the regulatory board is the Washington State Nursing Care Quality Assurance Commission (NCQAC).
RCWs (Revised Code of Washington): Statutes written by the Legislature and signed into law. RCW 18.79 covers the scope of practice, delegation, and licensing for RNs, LPNs, ARNPs, and nurse techs.
WACs (Washington Administrative Code): Rules that provide interpretive support for RCWs and carry the full force of law. WACs are made for nurses, by nurses, allowing for specific details regarding nursing care and public feedback outside of the legislative session.
